Two days ago, I reported on the severe damage to image quality seen with the Fujifilm X-Pro2 under certain high contrast lighting situations—a grid superimposed over a large area of the image.
It was plausible that the issue was some curious interaction specific to the Fujifilm XF 90mm f/2. But I have now reproduced the same issue with the XF 23mm f/1.4 and the XF 35mm f/2, adding examples with those lenses:
Images shown at sizes up to full 24MP resolution.
At least one reader made an invalid assumption: I reiterate that this issue occurs with in-camera JPEG from raw/RAF, not just raw files converted in ACR. So the problem is baked into the RAF file, and is thus irrevocable damage to the image.
I do not have any other Fujifilm X body to check whether the issue is unique to the X-Pro2, but my suspicion is that it occurs with other X camera bodies.
Will this issue be fixable with a firmware update? I deem it unlikely, because the behavior appears to be a lens-sensor reflection problem. I hope that I am mistaken.
